In all the' figures the same parts are represented by the same letters.

v To enable others skilled in the art to make and use my invention, I will proceed to' describe its construction and operation.

Theobject of my invention is to provide a means,

always convenient, for cuttiugthe thread used on a sewing-machine without waste and without the necessity of using scissors.

I make a spring, C, of steel or other suitable material, substantially of the shape represented in the drawings, and having the guard c projecting from it.

- Firmly attached to under side of spring C is knife D, the edge being toward the side from which 0 projects.

This spring I attach to top of presser-foot B by screw, or in other suitable manner, leaving the outer end free.

To give the knife room to play, I cut a slot under it in theedge of the presscr-i'oot.

To use this invention, when the thread is to be out, I draw it between the foot B and the spring C, the guard c aidingin so doing, and bring it against the edge of knife D, cutting it \vithouttrouble or loss of time.

What I claim as my invention, and desire to secure by Letters Patent, is-

The spring C, with knife D, and guard a, when constructed substantially as represented and described, and combined with the presser-foot of sewing-niachine.
